SPECIFICATION forming part of Letters Patent No. 382,677, dated May 15, 1888.V f

Application-filed October 12, 1886. Serial No. 215.983. (No model.)

To al@ whom it may concern:

Be it known that I, J Aeon BACHMAN, acit-izen of the United States, residing atStony Run, county of Berks, State of Pennsylvania, have invented a new, and useful Improvement ,in Harvesters and Binders,of which the following 1s a specification.

Thisimprovement is more particularly related to devices in combinationwith t-he bind ing-deck, whereby the tangling of the grain around the upper delivery-rolls of the elevator 1s prevented, and whereby the sheaf after being bound is automatically dumped from the same in a uniform manner.

Experts in the use of self-binding harvesters are aware that frequently the grain as it is carried from the platform up to the binding-deckl between the upper and llower aprons, particularly when the grain as harvested is in a tangled condition, will, instead of dropping out.l

from between the aprons upon the bindingdeck, continue its movement and pass over' the top roller on its way out of the machine,

and, clogging over the roll, prevent the oper-vv ation of the machine, which must be stopped and the clogged grain removed. They are also aware of the difficulty connected with the discharge of the' bound sheaves from the same cause, (tangled graim) which frequently hang atvone end, and in consequence drop upon the field in a very irregular manner.

My improvement shown in the drawingsaccompanying this specification and forming a part ot' the same shows very fully my mode of overcoming the above objectionable features .of the modern combined harvester and binder, like letters ofreferenceindicatingsimilar parts.

Fig. 3 represents in plan my automatic sheaf-dumper, which is secured to the under side of the binding-deck at the discharge end of the same, Fig. Il being afront elevation of the same, Fig. 5 representing a cross-section on the line a a of Fig. 4, with the abutment-arm in its normal position prior to the sheaf being forced against the same, Fig. 6

2, 3, and 4 until released by the cam; Fig. 10, a perspective View of the yoke detached from the frame. Fig. 1l represents in plan vmy im-v proved stripper or belt-clearer,which is placed inthe upper portion of the binding-deck in `,such a, position relative to the deliveringaprons that the teeth of the stripper as the same I is revolved shall catch the grainas it attempts to follow the apron over the upper roller and gather the same upon the binder-deck, the

teeth beingso arranged that as they r'evolve they shall protrude toward the apron and re-A tract within the body of the cylinder as they leave the apron,` thus leaving the grain seized by the teethl free to drop upon the bindingdeck. Bearings are provided for the shaft outside of the frame, and avsuitable drivinggear in connection with the cylinder to revolve the same. Fig. 12 represents a crosssection through the stripper on the line b b of Fig. '11, showing the teeth, shaft, and disks.

Fig. 13 represents in elevation and plan oneA of the disks which, superimposed upony each other, serve to make up the length of the stripper-cylinder. Fig. 14: is a plan and side elevation ofthe hollow shaft, which is securely held in bearings and upon which the strippercylinder as a whole revolves; Fig. 15, acrosssection of the hollow shaft with the stripper orI disentangling teeth shown in the positions they automatically assume as the stripper-cylinder is revolved upon the fixed shaft.' Fig.` 16 is an enlarged plan view of one end of the bundledischarger with a portion'iof the yoke broken away. Fig. 17 is an,` end viewof the bundledischarger, taken on line x x in Fig. 16.

A represents a lsupporting-fratrie for the sheaf-dumper, secured to the outer side of the bindertable, and which iis preferably made inV one integral piece, a bow-space, A', permitting its attachment to the lower face `of the binding-deck at the discharge end of the saine lwithout interfering with the operation of the usual binding machinery. To this frame suitable brackets, B, are secured, in which is supported a dumpingshaft, C, bent to conform to the shape of the frame A, as shown in Fig. 3. A yoke, D, having aV single arm, D', and a double arm, D2,with lugs D3, forming a recess, D, is secured also to the frame A, with the single arm D' uppermost, and the edge of the same in line with a transverse notch, A2, provided in the frame A for the passage of the connectingrod E to the inside of the frame.l

Asleeve, F, of suitable length abuts against the end bearing, B, on the right and against a cam, G, on the left, and is bored to revolve freely upon the shaft C. An abutment-arm, F', is secured to or made integral with the Sleeve, and is formed in length and contourso as to conform to that of the bound sheaf, said sheaf being pressed against the same by the discharg'eearms T. Lugs F2 are provided at one end of the sleeve next to the cam, separated from each other to forni a recess, F3, which in the normal state of the device embraces the spring H,which is enlarged for that purpose at one end, and has its other end secured to the bearing B by bolt H', and is thus locked in place.

The cam G is securely fixed upon the dumpingshaft C in free contact with the sleeve F, which is journaled loose upon the shaft. The cam G is provided with a side projecting lug, G', which clears the periphery of the sleeve and engages with one of the lugs F2. The earn is further provided with a pin, G2, whereby connection is made with the rod E, the opposite end of said rod being connected by ahookjoint, E', with a iiat spring, I, secured `by screws I' to the back of the frame A. A setscrew, J, is screwed from the front through the frame, with its point in contact with the lat spring I, whereby the resistance of the spring to the rotation ofthe cam G may be in creased o r diminished by manipulating said screw.

Upon the opposite end of the dumping shaft, and intermediate to the bearings B, a second abutting-arm, C', is adj ustably secured in place thereon by a set-screw, C, and central to the curve of the shaft C an arm, V', is secured by a set-screw, V2, in its hub V. Collars Q may be placed upon each side of the hub V and secured thereto by set-screws, the hub being adjustable upon the shaft between the same. A tail, V3, projected downward and connected with the trip-fingers B R by a link, S, having a slot,S,serves to secure an automatic reversal of the position of the arm V', said arm in its normal position lying between the trip-lingers B, the bars of which, as they descend to carry their heads below the bindingedeck of the machine, will, just before reaching their point of rest, operate upon the link S and forcibly pull "upon the tail V3, and thus ldraw around the arm V', lifting the sheaf clear of the deck and depositing the same upon the field.

The connection of the link S with the trip mechanism is shown in Fig. 2, in which the tripfingers (only one of which is shown) have moved downward far enough from their normal position, which is shown in Fig. 1, to permit the sheaf to slide down upon the arm V and rest against the arms G F', the sliding movement of the said sheaf being occasioned by the pressure of the material behind it. The pinat the end of the chain s, or other flexible connection which will communicate the motion of the parts, has slid along the slot S during the downward movement of the trip-fingers,

`and the continued lnovemeut of the said fin- "K,perforating the sides of the frame to the diameter of said cylinder for the purpose of introducing the same into place. Bearings L L support the ends ofa fixed shaft, M, held securely therein by set-screws L2, and the cylin-V der K revolves freely thereon. A pulley or gear, N, between the frame and bearing L serves by connection with a suitable revolving portion of the machine to give motion to the cylinder.

The revolving cylinder K is composedof a series of disks, K', adapted by thickness of the several disks to fill out the desired length of cylinder, a portion of the same, as N, being increased or diminished in diameter, or has attached to it a gear or sprocket wheel, for the purpose of .driving the same, as above described. 'Ihe disks forming the working portion of the cylinder have recessed seats K,

IOO

formed in one face of the same, asshown more clearly in Fig. 13, with pivots KB therein, and equidistant clamping-bolt holes K. Stripping-teeth P are pivoted in the recesses K2 on the pivots K3, and are so arranged relative to the cylinder K and fixed shaft M as to automatically project and retract their points from the face ofthe cylinder as the same is revolved. This result is attained by the use of a hollow shaft, M, of a length sufficient -to extend between the bearings, and which has its intermediate portion, M', which is coincident with the toothed portion of the cylinder, cut away upon its diametrical axial center, as shownin Fig. 14. A solid sectional shaft may be used,

the cut-away portion being grooved longitudinally for about one-half its depth; but I give preference to a hollow shaft of gas-pipe or its saaei'if .protruding points. r

The operation of the devic'es is as follows: The grain carried up to the binding-deck is met at the discharging-point between the upper and lower aprons by the stripper-teeth P, which at that point protrude to their full extent from the cylinder K, and which, catching any grain following the upper apron above said point of discharge, will'strip the same away. and deposit it upon the binding-deck within reach of the packers U U. The teeth, losing their foot-support as they pass toward the rear, fall within their respective recessesKz, and the grain falls by gravity upon the deck. The usual packers, U U, are then broughtinto action in combination with the usual needlearm, and the s heaf is made up and pressedto the rear by the dischargers T preparatory to a repetition of the operation. The result of this is that the consecutive sheaves as formed are pressed against the preceding ones, and they are successively discharged, under the old system, some with the butt, others with thehead end, first striking the ground, while withy tangled grain they very frequently hang and refuse to drop unless assisted by the driver.

In the use of my automatic d'umper all uncertainty is done away with. rIhe buttof the sheaf is pressed against the abutting arm F', the head of the sheaf against the abutting arm C', While the center of the sheaf lies upon the arm V', placed between the trips R It, the pressure of the sheaf being continued by the efforts of the discharging-arms 'I to rid the binder-deck of the same. The force of the spring I is overcome, and the shaft C, being carried around by the arm C', carries with it the cam G, which unlocks the spring H fromA the sleeve, raising it into the recess D@t of the yoke, when the arm F' drops until one of the projections F2 of sleeve F strikes against the lug G' of cim G. The spring H retains the sleeve F and its arm, and prevents that end of the sheaf from moving until the arms C' and V' have moved a considerable distance and the cam G has revolved sufficiently to raise v the spring H out of the notch F3 on the sleeve y and into theguide-slot D1 of the yoke.

The arm F' 'then moves suddenly before the sheaf, and its sudden movement is simultaneous with the following sudden movement of the arms C and V'. As the bent portion of the shaft passes downward it partially raises the sheaf by the arm V', and at the same moment, the trip-fingers having descended to put the trips out of the'way, the rod S, connecting the tail V3 of the central arm, V', receives a is loosely-connected by the Aslot S and chain s, and theA result is that the sheaf is thrown completed clear of the machine and uniformly upon the ground'. The dumping of the sheaf having relieved the'tension upon the spring I, it at once returns` the shaft into positionby its pull upon the pin yG2 of the cam G, and the lug G of. the latter, in its return movement, presses against the lug F2 of the sleeve F and .returns the sleeve and its arm F' into place for a repetitionof the movement. lheforward-1ug,F2, lifts the springvHas ltgpasses- .under the same, which is then again locked in .therecess F3. .At the Sametime as the bent 'suddeh'pn fm'm't'he tr'ipr-big'with which it shaft with its fixed arm C israised into its normal position it carries with it the-central arm, V', which rises above the frame A,when, being free and the tension of spring I n ow be-l ing only slight, it falls by gravity into lts position between the tripsR R, ready to receive f the next formed sheaf and discharge thesame from the binding-deck.

What I claim is- 1. In aharvester, the combination of the nou-revolving delivery-cylinder shaft having its central portion cutaway upon one side, the cylinder K, comprising a series of diskssuitably connected together by bolts passlng through holes K4 and revolving upon the said shaft, and the stripping-teeth P,pivotedfou vided with heels P', so that the teeth are pressed outward by the circumference ofthe shaft, substantially as and for the purpose set forth. v 2. In a harvester, the combination of the'V tubular non-revolving delivery-cylind er shaft, havingits central portion cutaway on oneside, the cylinder K, comprising a series of disks pro- -pins projecting from the said disksand pro- Y vided with recesses K2 and pins K3, the said pins in each disk being spirally in advance of the pins in the next disk, and the disks being connected together by bolts passing'through holes K4 and revolving upon the said shaft,

and the stripping-teeth P,pivoted on the pins projecting from the said disks and provided with heels P', so that the teeth are pressedoutward by the circumference ofthe shaft, substantially as and for the purpose set forth.
